The increasingly sophisticated uses of medical plastic tubing demand that processors exercise ever-greater control over key process factors, including quality, precision, repeatability, traceability, and cleanliness. Often, they must do so while producing increasingly complex tubing configurations including: micro-bore tubing sizes (less than 0.060” in diameter) for heart and brain catheters; multi-lumen structures for diagnostic, interventional, and therapeutic uses; complex bump profiles; and while meeting tight tolerances for tube structure and material properties
